PhilsComputerLab: Ok thanks for that.
Will read through the thread on it, seems a bit tricky to get going but worth it.
Not that bad.
* Get the latest Python 2.7.XX installer from www.python.org. It *must* be 2.7.XX Not 3.X.XX.
* Remember to let Python add itself to your PATH.
After the installation, run these in a "Command Prompt" window (Win+R > "cmd"):
* Run "pip install html2text" and "pip install html5lib".
* CD to the directory where you want your GOG installers stored.
* Save the gogrepo.py file here.
* Run "python gogrepo.py login" and follow the instructions.
* Run "python gogrepo.py update -os windows linux mac -lang en da" to fetch the info about the English and Danish language versions on all three platforms. (Looking at the website, it looks like GOG knows these language codes: en cz da de es fr it hu nl no pl pt br ro fi sv tr ru ko cn jp.)
* Run "python gogrepo.py download" and wait..........
In the future, you only need to run the "update" and "download" steps.
There are more options (e.g. for optimising the update step, but these are enough to get started).
